Emergency Tensioning Device, belt
force limiters
The front seat belts and the outer seat belts
in the rear are equipped with ETDs and belt
force limiters.
! If the front-passenger seat is not
occupied, do not engage the seat belt
tongue in the buckle on the front-
passenger seat. Otherwise, the Emergency
Tensioning Device could be triggered in the
event of an accident.
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrect seat
positions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
Belt force limiters, when triggered, help to
reduce the peak force exerted by the seat belt
on the vehicle occupant.
The front belt force limiters are synchronized
with the front air bags, which take on a part
of the deceleration force. Thus, the force
exerted on the occupant is distributed over a
greater area.
The ETDs can only be activated when:
R the SmartKey is in position 1 or 2 in the
ignition lock.
R
the restraint systems are operational; see
"SRS warning lamp" (
Y page 34).
R the belt tongue is engaged in the buckle on
each of the lap-shoulder belts in the front.
R
the front-passenger seat is occupied and
the belt tongue is engaged in the buckle on
the front-passenger side.
The ETDs are triggered depending on the type
and severity of an accident:
R
in the event of a head-on or rear-end
collision if the vehicle decelerates or
accelerates rapidly in a longitudinal
direction during the initial stages of the
impact
R
in certain situations if the vehicle overturns
and the system determines that it can
provide additional protection
If the Emergency Tensioning Devices (ETDs)
are triggered, you will hear a bang, and a small
amount of smoke may also be released. Only
in rare cases will the bang affect your hearing.
The smoke that is released generally does not
constitute a health hazard. The + SRS
warning lamp lights up.
G
Warning
Pyrotechnic ETDs that were activated must be
replaced.
For your safety, when disposing of the
pyrotechnic ETDs always follow our safety
instructions. These are available at any
authorized Mercedes-Benz Center.

R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
